Antique circa 1920 10K Tuxedo set. This dapper antique set is crafted and stamped for 10K gold. They feature 10K yellow gold backs and white gold faces. The white gold frames are a striking border to the deep rich black concave centers. I am not sure if they are onyx or glass. They will come to you as found in their old presentation box. The face of each side of the cuff links measure app. .5'' and the center connecting chain is app. .5'' long. Their matching shirt studs are app. .25'' in diameter. These early 1900s gentleman's accessories are in lovely condition with age appropriate wear.
